VALVE.

Specification of Letters Patent. Patented Dec, 16, 1919,

' Application filed October 12, 1515, Serial No. 55,535. Renewed. May 19, 1919. Serial No. 298,340.

T0 all whom z't may concern:

Be it known that I, DANIEL F. MoGILL, a citizen of the United States, residing in the city of Portland, county of Multnomah, and State of Oregon, have invented certain new and useful Improvements in Valves, of which the following is a specification.

The principalobject of my invention is to provide in combination with a valve body having a passageway therethrough, and a Valve seat formed in said passageway, a valve member adapted to be moved up into the valve body and wholly out of the passageway through said valve body, whereby to give full clearance in said passageway through said valve body. In the present'application I have provided an improved construction of valve member, with improved means for operating the same from its seated to its out-of-the-way positions.

In order that others may fully understand my invention, I have illustrated the same in the accompanying sheet of drawings, which I will now describe.

Figure l is a side elevation of a valve en1- bodying my invention, with a portion broken out to show the interior construction and arrangement thereof; i

Fig. 2 is a top plan view of the valve body with thetop and valve mechanism removed;

Fig.3 is a back view of the valve member,

Figs. 4. and 5 are fragmentary face and end views of the lower end of an operating stem for moving the valve member; I Fig. 6 is a detailed view of a part adapted to be set into the part shown in Figs. 4

and 5;

' Fig.7 is a connecting link memberadapted to connect the part shown in Fig. 6, with the valve member shown in Fig. 3 and Fig. 8 is an end view showing the parts shown in Figs. 6 and 7, asthey are put together, and adapted to be set into the part shown in Figs. a and 5.

1 Referring now more in detail to the drawings, 1 designates a valve body, of globe valve type, having a passageway through the same longitudlnally thereof. 2 designates a valve seat member screwed into the 2, said guideways turning at their inner ends toward said valve seat, as clearly indicated in Fig. 1. p

The upper portion of my valve member, as here shown, is constructed substantially like the present modern construction of such valves with the exception that I haveprovided an operating sleeve 5, provided at its upper end with an operating wheel or hand piece 6, and threaded interiorly to receive a screw member 7, saidsleeve being seated at its lower end in a cap, or top, member 8, as clearly illustrated in Fig. 1. The, lower end of said screw is provided with a head mem her 9, of substantially the form shown in Figs. 1, 4: and 5, and having the open sockets 10, at its opposite ends, and-the cut-away portion 11', as indicated in Figs. Land 5, said head having a thickened portion, as at 12, to give it increased strength. Theopposite ends of said head are adapted to move in the'guideways 4-4, in the oppositev sides of said valve -member. A yoke member 13, shown in Figs. 6 and 8, and having the arms I l-14, is adapted'to be set into the head 9, with the arms 14 -''ll seated in-the sockets 10 10, said yoke being provided'in itsopposite sides with two sockets, as 15,v adapted to receive the ears 16-16, of a link member across its lower: side which fits; under the lower edge ofthe head 9, inthemanner indicated in "Fig. 1.' The valve member 20, is provided at each ofjits opposite sides. with two laterally projecting lugs, .21 and 22,

adapted tomove, respectively, in the guideways 3 andl, ,formed in the opposite sides Thus it will be seen that theparts connecting the valve member 20, with the head 9, upon the lower end of the screw; 7, are readily detachable one from the other, and at the same time form a connection vvhichwillv allow any necessary movement of thevalve member 20, in order to make a perfectseat 2, as indicated in dottedlines'in Fig. 1. 1

It will also be noted that the screw-.7, which carries the-head 9, and the valve member 20, isadapted tobe raised and lowered 7 within the sleeve 5, as said sleeve 5 turned of the interior wall of said valve member.

of said valve member 20, .uponthe valve seat by means of the wh el, or hand member, 6, thus lifting the screw, aswellasthe valve member, wholly out of" the"pas"sageway through the body of said valve and giving fullest possible clearance of said passageway hroug sa al e bo y The ob 'eraf'fiioh 6f the device 'iii'ay' be briefly, describedgas follows; Assuming that j said valvememberibeinglgnided by-.;means.
